I have one that I finally started shooting about a month ago. fiocchi 50 gr. vmax do well. Although it seems to start stringing when the barrel gets warm. Not many rounds through it, maybe handloads would fix the stringing? I also noticed the mag well does get in the way a little, nothing to slow you down though. I wish I would have held out for one with iron sights rather than the ghost rings. at longer ranges (100 yds.) the ghost rings for me just don't cut it.
